In the framework of the computation of the solar capacity per region, it is totally correct to take the global inclined component of the solar radiation. It will estimate what should actually be collected by your titled solar panel (do not forget that azimuth of the plane is 180° to aim the South direction). But we are not sure with your 0.7 coefficient. Generally, an approximate estimation of the annual production of panels is: Annual production = annual GTI (Wh/m2) * surface (m²) * Epv (efficiency photovoltaic panels) * Pr (Performance ratio) …where: Epv belongs to the interval [0.1, 0.17] (0.19 for the best solar panels), a typical value is 0.12, and, Pr gives an indicator of the global quality of the production chain (inverters, cabling, near shadowing effects…) with a value between [0.5, 0.9] and a typical value of 0.8.
ou: Production = GHI ou GTI * Puissance nominale en kW crete * Pr
